Brief description of study

What is the purpose of this study?
This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients withgerminomatous germ cell tumors (NGGCT) that have not spread to other parts of the brainbody (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dosehemotherapy followed by conventional RT in patients who did not respond to inductionhemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells, byg them from dividing, or by stopping them from spreading. Radiation therapy uses highgy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies havehown that patients with newly-diagnosed localized NGGCT, whose disease responds well tohemotherapy before receiving radiation therapy, are more likely to be free of the diseaseger time than are patients for whom the chemotherapy does not efficiently eliminateduce the size of the tumor. The purpose of this study is to see how well the tumorsd to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dosehemotherapy and a stem cell transplant before RT to the whole brain and spine. Givingbased on the response to induction chemotherapy may lower the side effects ofdiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.

THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study

What will happen during the study?
INDUCTION CHEMOTHERAPY: Patients receive carboplatin intravenously (IV) over 15-60 minutes on day 1 and etoposide IV over 90-120 minutes on days 1-3 of cycles 1, 3, and 5. Patients alsove ifosfamide IV over 60 minutes and etoposide IV over 60-120 minutes on days 1-5 ofycles 2, 4, and 6. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
Patients are assigned to 1 of 2 plans (ventricular + spinal canal irradiation [WVSCI] or high-dose chemotherapy with peripheral stem cell rescue [HDCSCR]) based on response toduction chemotherapy:
  • Patients who achieve radiographic CR/PR with marker normalization proceed to WVSCI. Patients who achieve radiographic CR without marker normalization proceed to HDCSCR.
  • Patients who achieve less than radiographic CR/PR with marker normalization proceed tod-look surgery (unless contraindicated). If second-look surgery reveals matureviable tumor, proceed to WVSCI. If second-look surgery reveals viableumor, proceed to HDCSCR. Patients who are unable to undergo second-look surgery areved from protocol therapy but remain on study for follow-up.
  • Patients who achieve less than radiographic CR/PR without marker normalization proceedd-look surgery (unless contraindicated). Patients then proceed to HDCSCRgardless of whether or not a second-look surgery is performed.
  • Patients who achieve radiographic PR without marker normalization proceed to second-lookurgery (unless contraindicated). Patients then proceed to HDCSCR regardless of whetherd-look surgery is performed.
PLAN A (WVSCI THERAPY): Within 6 weeks of the end of induction chemotherapy or second-lookurgery, patients undergo WVSCI once daily (QD) for 5 days weekly (17 fractions followed by a boost dose for 13 fractions) for 6 weeks in the absence of disease progression or unacceptable toxicity.
PLAN B (CONSOLIDATION THERAPY [HDCSCR]): Within 6-8 weeks of the end of inductionhemotherapy or second-look surgery, patients receive etoposide IV and thiotepa IV over 3 hours on days -5 to -3 and undergo peripheral blood stem cell (PBSC) transplant on day 0. Patients then undergo radiation therapy QD for 5 days weekly (20 fractions followed by a boost dose for 10 fractions) for 6 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for up to 10 years.
